I run a web shop. I have competitors. We have tough price competition.
I want to know when a competitor offers for a given product a cheaper price than me.
I need a kind of price robot.
I'll feed the system with the URLs and html id's or classes of each of the competitors price tags (e.g. <div class="article_details_price"><strong>269,00 € *</strong></div> or <span class="price" id="product-price-23"> 119,00 € </span>)
The system need to display the product prices of the given competitors and highlight the cheapest one. The comparison shall be made once every day. In case a cheaper price than mine is detected, I need to get an email about that fact.
A web based solution is preferred.

Would accomplish this with some html parsing scripts in Perl. I assume you already have a (web) server running where these scripts can be installed.
